Wow Tara you have a really high opinion of yourself. The fact that you believe most (if not all) male OB's get some sort of cheap thrill by performing a pelvic exam is quite objectionable.
Your argument that men should stay out of OB because it is a field that only deals with women is insane. No one "enjoys" getting a genital exam. As a male should we only request a male FM doctor perform hernia or prostate checks? Are Psychiatrists all perverts because they discuss intimate things with the patients like sexual paraphilias? Next you would say Pediatricians are pedophiles because they look at genitals all day long. I don't know where you are getting this viewpoint that there is so much sexuality surrounding clinical exams.
We all might encounter a patient we would consider attractive, but you know there is something very different about seeing a patient in a hospital or a doctor's office. There are things you don't say in a clinical setting that you might in a social setting or things you would never do that you might in a social setting (forgetting as well that a great majority are committed to SO anyway). This is what being a professional is all about. People always joke about how Laywers, Insurance salesmen, Care Salesmen, etc are sleaze bags. Well in contrast Physicians are always listed in the top 3 most respected professions in any society poll. Why? Because we are trusted with dealing with the most sensitive, private and intimate details of a patient's life and this is not just limited to OB. The vast majority of Physicians maintain this respect.
You ask what could a male OB bring to the table? Well as other posters have pointed out perhaps a male and his partner struggled with infertility. Maybe his sister died of Ovarian Cancer. Maybe it was a toss up between Urology and OB, but matching into OB is several orders of magnitude easier to match into. When you practice Reproductive Endocrinology, GYN Onc, etc you are really getting away from this idea of just doing genital exams all day long. A male who went through an infertility work up and struggled to have children is especially qualified to work in that field. And there is certainly nothing sexy about Ovarian/Uterine/Cervical Cancer.
When my wife was pregnant we went to a practice with a male and a female OB. Both of them were excellent and my wife had no issue whatsoever seeing the male OB. He was nothing but respectful and offered wonderful care. In fact he seemed way more empathetic and understanding than the female OB (although she was still very good). I really think some women pick up on that. Especially considering a lot of female OB's fall into that stereotype of being Type A, ultra-intense, non-empathetic, etc. But let's face it, that describes most surgeons and doctors in general are over-achievers. So when a women comes in with menometrohagia, etc I could see the female OB having the attitude of saying "Just suck it up".
Are you sure you are an OB resident? It seems unlikely given your over-sexualization of the clinical exam. When I was on OB and I saw a case of BV or saw a pregnant, stressed out woman in labor screaming in pain as she is crowning and I see a nice mixture of blood, amniotic fluid, urine and fecal matter, the last thing that goes through my mind is "Wow this is so hot".
Furthermore you assumption that is an only female specialty is somewhat inaccurate. GYN, sure. But as OB you have some responsibility to the father. As a male I appreciated being talked and acknowledged by the OB doc and LD nurses. Secondly what about your responsibility to the fetus? Now of course as soon as the baby comes out if there is a problem he/she goes right to the Pediatrician. However while the baby is in utero it is your responsibility and clearly half of them are male. If you can get sued for a bad outcome of the baby in utero, in my opinion that's your patient. When my son was born it was the OB that performed the circumcision so clearly there is some overlap b/w Peds and OB.
I had a number of male classmates develop an interest in OB during their rotation. All of them said the cool thing about OB is being able to share in the birth of a child. That is an amazing thing to be a part of and from what I have seen it's what most OB's are really passionate about. And I am sorry, sharing in the birth of a child is not something only females have monopoly on. BTW, none of my male colleagues said they wanted to do OB because they were super excited about looking at vaginas all day.
I am not sure where you developed this hatred for men, but it is insane in this day and age for you to be pushing an agenda of segregation. Diversity in any field is always better and if you really cared about women's health you wouldn't want to eliminate an entire pool of qualified candidates. I know deep down you believe woman are smarter and make better docs (in all fields), but that simply is not true. Men and women are equal in their abilities and every specialty should have access to the best applicant. If you get your way though, one saving grace is that male med students can skip the OB rotation J
